20110296686 | ROTATIONALLY BALANCING A ROTATING PART - A method is provided of rotationally balancing a rotating part. A rotor hub or ring and a plurality of rotor blades for assembly onto the hub or ring are provided, each blade having an unfilled internal cavity. The respective masses and moment weights of the blades with filled internal cavities are then predicted. Next, the rotor blades are assembled onto the hub or ring to form the rotating part. The relative positions of the assembled blades are determined on the basis of their predicted masses and moment weights with filled internal cavities. The internal cavities of the assembled rotor blades are then filled. | 12-08-2011 |
20120034091 | AEROFOIL, AN AEROFOIL SUB-ASSEMBLY AND A METHOD OF MAKING THE SAME - An aerofoil sub-assembly of a blade, in particular an aerofoil blade for a gas turbine engine. A multi-layer construction including first and second skin panels which together define the external surfaces of the aerofoil and aerofoil leading and trailing edges. Between the skin panels at least there is at least one web-forming membrane which has a multiplicity of fingers trapped between the first and second panels at one of the edges and which extend away from the edge region. The fingers each have “dog-leg” shapes which are overlaid immediately behind the blade leading edge to form a transition zone providing additional support to resist crumpling of the hollow blade in the event of an external foreign object striking the leading edge. | 02-09-2012 |

20090016894 | Component with internal damping - A method of manufacturing a component such as a gas turbine fan blade. The method comprises: disposing a plurality of webs between a plurality of panels; and deforming the panels and the webs by applying internal pressure between the panels, thereby forming a series of internal cavities ( | 01-15-2009 |

20100021693 | Aerofoil sub-assembly, an aerofoil and a method of making an aerofoil - A method of making an aerofoil comprises the steps of providing first and second skin panels and first and second web-forming membranes. The web-forming membranes each have a series of elongate slots formed longitudinally therein so as to define a series of alternating wide and narrow strips. The wide strips of one membrane are arranged against the narrow strips of the other membrane and the skin panels are arranged either side of the two web-forming membranes. Parts of the web-forming membranes and parts of the skin panels are treated with a release layer and the sub-assembly is compressed and heated so as to effect diffusion bonding between those parts of the membranes and skin panels which are not treated with the release layer. The sub-assembly is then heated and inflated so as to draw the first and second skin panels apart and that, in turn, causes the web-forming membranes to form webs internally. | 01-28-2010 |
20120135198 | METHOD OF MANUFACTURING A COMPONENT - A method of manufacturing a component having first and second layers, the first and/or second layers including one or more depressions provided on a surface of the respective layer. The method including: arranging the first and second layers so that they face one another and with the depressions on inner facing surfaces of the layers; diffusion bonding the first and second layers together about their edges; applying a first differential pressure across each of the first and second layers to evacuate an inner space defined by the layers, thereby forming one or more depressions on an outer facing surface of the first or second layer; and applying a second differential pressure across each of the first and second layers to expand the inner space defined by the layers. | 05-31-2012 |
